I have found quite a few Lora’s on the internet advertising they use these. I will try it on my 1W ebyte’s first to see if it blows them.
I have tried a 18db antenna that can handle up too 50W of power @0.1W. It helped a lot. But power is no issue the sun is always making more of it.
I also have my HAM license so I am also allowed to amplify experimentally up too 1.5 KW in this band. But I think a solid 10W will do fine for my needs. Its like a Russian Airplane; Its not that it really needs 10 jet engines to fly, but is it not awesome to fly a plane with 10 jet engines.
Just trying to see how far away reliably I can drive a tractor, plus run a higher data and rtk correction refresh rate as well without cellular. RTK seems to be pretty solid 2" pass to pass over cellular at 30km, but if i can hit that distance with Lora. $80/month savings just on two sim cards. Add 3 combines, a Grain cart, a couple swathers and subscribing neighbours equipment it adds up quick.
